DOUGH-ARAISVING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 521,972, dated J' une 26, 1894.

Application led March S0, 1894. Serial No. 505,735. (No model.)

in the'county of Fond du Lac and State of for a lamp D or other heater.

Wisconsin, have invented certain newand Auseful Improvements in Dough-Raising Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciication. y

My invention relates to an apparatus for raising dough, and it consists in certain details of construction hereinafter set forth vand particularlypointed out in the claims.

In the drawings, Figure l is a perspective View of a cabinetv embodying my improvements. Fig. 2 is a detail.

The body A-is made of a height convenient to serve as a table, say three feet high. It is preferably about twenty one inches deep, and forty-two inches long. These dimensions may be varied, however, and are given merely to indicate what I consider to be a desirable size. A horizontal partition a divides the interior into upper and lower compartments, the lowerbeing subdivided into three lockers by vertical partitions c. The two side lockers are provided with removable shelves a2 for storing bread, cake, &c., and each locker has itsown door as shown. The middle locker is provided in its bottom with a damper B, and its top C is a butterliy valve, fitting an opening in thepartition a and` hung on a horizontal spindle c, which has a handle c outside of thefcabinet. 'In the valve are a number of small perforationsc locker contains a shelf or other support a3, A damper or register E leads from the middle locker into one of the side lockers. Each end ofthe up; per compartment above the side lockers is occupied by a` box orbin F preferably made of metal and loosely lset in so that they can be lifted out when necessary. These bins are for flour, meal and the like.

The middle Between the two cross rails 0.4 hang curved 5o ribs G' to support the removable pan Hin which the dough is mixed and left to raise. l

The pan is suspended over the heater, and the heat is regulated not only bythe damper B and valve C but also by a damper I in the 55 back of the cabinet above the valve C. A spindle t and a handle t" outside the cabinetA give control of this damper. A bell or guard K suspended from the ribs G deiects the rising column of heat and prevents it from un- 6o `duly heating the lower partof the pan H. A thermometer L is let into a slot in the front of the cabinet, and indicates the temperature of the heating chamber below theV pan.

The small perforations c2 prevent the draft 46g vfrom being choked when the valve C is? entirely closed, as shown in the drawings.

A lid A closes the tops of the bin F and the pan H.

Having thus described my lnvention, what 7o l. A cabinet for mixing and raising dough, comprising a central heating chamber, a pan depending into said chamber, a locker below said chamber, a heater in said locker a but- 7 5 teriiy valve between the locker and the heating chamber, and dampers for the entrance and escape of air, substantially as described.

2. A cabinet for mixing and raising dough consisting of the combination with two re- 8o movable bins, of a pan depending into the space between said bins, a locker below each bin and below the pan, a heater in said latter locker, a damper in the bottom of said locker,

another damper in one side thereof, a' butter- 85 fly valve forming the top of said locker, and a damper in the back of the cabinet below the pan, substantially as described.

3., In a cabinet for mixing and raisingdough,

the combination with a pan, of a locker below 9o said pan, a heater in said locker, and a butterfly valve containing a number of small perforations, forming the top of said locker, substantially as described.
